The skull is an example of which type of joint?

The skull is classified as a synarthrotic joint, which refers to a joint that is immovable or only allows for very limited movement. The joints in the skull, particularly the sutures, are rigid and do not permit any motion, which is characteristic of synarthrotic joints. These connections help protect the brain and provide structural stability to the skull.

In contrast, diarthrotic joints are characterized by a full range of motion and include synovial joints, which have a joint cavity and are commonly found in areas like the knees and elbows. Amphiarthrotic joints allow for slight movement and are typically found in structures such as the pubic symphysis and intervertebral discs, which provide a balance of stability and flexibility. The nature of the skull’s joints aligns specifically with the definition of synarthrotic joints, reinforcing why this classification is accurate.
